[State of the art and perspective of pulp regeneration].

Recently, various levels of success have been achieved in dental pulp and dentin regeneration using latest techniques such as pulp revascularization, stem cell transplantation and cell homing. These cutting-edge technologies utilize stem cell mobilization, homing and directional differentiation, stem cell sub-population isolation, expansion and transplantation, modification and optimization of biomaterials and/or synergetic effects of biological cues. The objective of this review is to identify approaches for clinical translation and improve the success rates of pulp regeneration. We will focus on either basic and clinical research progress of dental pulp revascularization, or translational challenges and strategies of stem cell transplantation and cell homing in dental pulp regeneration.
